I have a very nice 1915 Model TT stake bed truck for sale. It runs, drives and stops. Asking $13,599/offer.
Post a picture so we can see what you have. There's no such thing as a 1915 Ford Model T TT (Ton Truck). The very first TTs were produced in late 1917, with actual production starting in 1918.
Also, you'll get better results posting your truck for sale in the classified section.
Also include is a dated 1915 Ruckstell two-speed rear axle.
I meant to say 1917, Sorry.
Pretty sure Ruckstell axles for TT were not available until perhaps 1922 - 1923 or thereabouts. Still would like to see photos and the Ruckstell is a plus regardless if it was available when your truck was new.
Ford built only three TT trucks in fiscal / model year 1917. If your truck is one of the three 1917 TT trucks it is a rare gem indeed.
